8 Claims.`

The present invention relates to belt conveyors.

More specifically it relates to an arrangement for` securing conveyerflights, pegs, and buckets to a V-belt, a flat belt, or a round belt.

The conveyors in use today are most generally of the chain type. Thesechain conveyors, when used on a mobile type of machine, add greatly tothe weight of the machine, are noisy in operation, and require constantlubrication.

It is, therefore, an object of the present invention to provide aconveyor that is of light weight, and which will operate with a minimumof noise.

Another object of the invention is to kprovide a belt to which may besecured at any point thereon, conveyor flights, pegs, and buckets.

Other objects will become apparent to those skilled in the art after aconsideration of the following description and explanation, referencebeing had to the drawings appended hereto, in which:

Figure lis a perspective View of the V-belt conveyer with a conveyer pegsecured thereon;

Figure 2 is a longitudinal section of the structure shown in Figure l;

Figure 3 is a sectional view taken along line 3--3 of Figure 2;

Figure 4 is an end view of a conveyer peg applied to a flat belt;

Figure 5 is an end view of a conveyor peg applied to a round belt;

Figure 6 is a front view of a bucket type conveyer secured to a belt;

Figure 'l is a side view of the structure shown in Figure 6;

Figure 8 is a sectional View of a V-belt type elevator; and,

Figure 9 is a sectional View taken along the line 9-9 of Figure 8.

ln the drawings and speciication like numerals refer to like part-sthroughout.

Referring now to Figure l, reference numeral Il? indicates a V-'oelttype of conveyer to which is secured a conveyer peg II. The V-belt Ii)is provided with a pair of grooves i2 formed in the upper portion of theconverging sides thereof. The grooves I2 form laterally extending ribsor beads I3 and are provided on the V-belt IG above that portion of thebelt which normally engages a pulley.

The conveyer element shown is in the form of a peg Il and is of U-shapeand the ends thereof are provided with arcuate portions I t. The sidesof the U-shape peg I l are bent at i5 and the portions I thereof arebent inwardly closing the end of the peg i I. Aligned countersunkopenthe ings Il' are provided in the sides of the U-shaped peg II. Thepeg Il is placed on the belt Iii, ythe arcuate portions Ill thereofengaging and gripping the ribs i3, and the portions I6 engaging the topof the V-belt itl. To prevent the peg II from moving on the belt it, aretaining clip I8 is provided. The clip l 8 contacts the top of the beltI0 and the countersunk portions of the openings il. A rivet It isinserted in the openings and peened into the countersunk openings I1which brings the arcuate portions ifi into engagement with the ribs i3of the belt lil. The peg II is securely held on the belt I0, since theretaining clip i8 in conjunction withv the arcuate portions I4 preventsthe peg from moving vertically or fore and aft with respect to the beltI0.

Figure 4 illustrates an application of the invention to a flat belt. Theat belt Ia is provided with grooves or recesses Ita and ribs or beadsIta along the top surface thereof. The peg I I is secured on the ribsElia in the same manner as kdescribed above for the V-belt.

Figure 5 illustrates another application of the invention, in this case,to a round belt. The round belt Ib` is provided with grooves I2b andribs i317 along the top surface thereof. The peg II is secured on theround belt Ib in the same manner as described for its application to theV-belt. It is to be noted that in securing the peg II on the V-belt,flat belt and the round belt that the peg II in no Way interferes withthe operation of the belt. `The peg II may also be secured at anydesired point in the belt, as the groove extends the length of the belt.

In Figures 6 and 7 there is illustrated a bucket 2i! which is secured onthe V-belt Il] by a bracket 2 I. The bracket 2l is provided with arcuateportions 22, which straddle the ribs I3. The ends 23 of the bracket 2lare bent inwardly and contact the top of the belt I8 to prevent shiftingof the bracket ZI with respect to the belt I0. The bucket 20 isspot-Welded to the top surface of the bracket 2|.

In applying the present invention to an elevator of the night type thepegs II can be used by spot-Welding nights to the end thereof. Referringto Figure 8 there is illustrated an elevator 24. Pulleys 25 arejournaled at the ends of the elevator 24. An adjusting mechanism 26 isprovided in connection with one of the pulleys 25 to effect movement ofsaid pulley. A V-belt I0fis connected between the pulleys 25 on which isconnected as previously described, the peg II. The flights 2l arespot-welded to the portions I6 of the pegs. Plate members 28 are Weldedto the insides of the elevator 24, and extend toward the belt l belowthe flight 21 and form a bottom for the elevator.

From the foregoing description it is obvious that a novel beltconstruction has been provided, and also a simple and inexpensive methodof securing pegs, flights, and buckets on the belt. Other methods ofcarrying out the present invention may occur to those skilled in theart, however, I do not intend to limit the invention to the precisedetails shown and described except as set forth in the appended claims.

What is claimed is: 1. A belt for a conveyer having a first side, secondand third sides extending in spaced relation from the first side andadapted to engage a pulley, and grooves formed in the second and thirdsides above the pulley-engaging portions of said second and third sides.

2. A belt conveyer comprising a belt having a rst side, second and thirdsides extending in spaced relation from the first side and adapted toengage a pulley, grooves formed in the second and third sides above thepulley-engaging portions of said second and third sides, an elementstraddling the belt and engaging the grooves in the second and thirdsides of the belt, and means for securing said element on the belt.

3. A belt conveyer comprising a b-elt having a first side, second andthird sides extending in spaced relation from the first side and adaptedto engage a pulley, grooves formed in the second and third sides abovethe pulley-engaging portions of said second and third sides, a U-shapedmember straddling the belt and engaging the grooves therein, and meansconnecting the sides of the U-shaped member for securing the member nthe belt. l 4. A belt conveyer comprising a belt having a rst side,second and third sides extending in spaced relation from the first sideand adapted to engage a pulley, grooves formed in the second and thirdsides above the pulley-engaging portions of said second and third sides,a U-shaped member straddling the belt and engaging the grooves therein,a securing element connecting the sides of the U-shaped member forsecuring said member on said belt, and a retaining clip disposed betweenone side of the belt and the securing element.

5. A conveyer comprising a V-belt having a rst side, second and thirdpulley contacting sides extending in spaced relation from the rst sideand grooves formed in the second and third sides above thepulley-engaging portions thereof, an element straddling the belt andengaging the grooves formed therein and the first side of the belt, andmeans for securing said element in the grooves. A

6. A conveyer belt having a surface adapted to contact a pulley, asecond surface spaced from the first surface, and recesses formed in thebelt between the rst and second surfaces, an element straddling the beltand engaging the recesses, means for securing said element to saidrecesses, and retaining means disposed between the second surface of thebelt and said element.

7. A belt type conveyer comprising a flexible belt having a pulleyengaging inner portion and an outer portion formed with spacedlongitudinally extending attaching beads, and a plurality of conveyerelements secured to said beads.

8. A belt type conveyer comprising a belt consisting of flexiblematerial, said belt being provided with an inner pulley engaging portionadapted to engage a driving and a driven pulley and an outer portionincluding continuous recesses forming spaced laterally projectingattaching portions, and a plurality of conveyer elements havingattaching portions fitted over the attaching portions on the belt.
